First shown as a concept motorcycle as the EICMA show in Italy in 2018, the Aprilia RS 660 concept motorcycle generated a lot of interest from the public.  According to French website Moto-Station and as reported in asphaltandrubber.com, development on the RS 660 is on going. 

While there is a paucity of details on the RS 660, being a twin is a given since slicing the RSV4 mill in half would not be a big deal. As for power, a number a little above 100 hp would be a good guess as that is the median for bikes in this class.

Given that Aprilia expects this to be “the first model of a new platform,”, we can assume that a naked 660 will be coming some time soon. As for pricing, it is said the Aprilia RS 660 will be marketed to a specific price point, possibly in between work-a-day bikes like the Honda 650 and right up against super sports machines like the Yamaha R6.
